I installed a delta flow 40 flowmaster onto the 2.5" factory tubing. I would say that it is loud but not obnoxious by any means. You can tell its a v8 for sure, but inside the cab its not all that much louder.

Haha I was just messing around with you when you said real men buy full exhausts lol, I know what you mean though. I just want my Jeep to be louder, but still sound good, so i figured the 2.5inch cat back from IRO with the flowmaster 40 series muffler would be perfect?
